Inside a Carbon-Based Ozone Catalyst: Three Pore-Forming Routes and Cobalt-Nickel Dual-Atom Sites

2026-09-09

Carbon-based ozone catalysts often look good on paper and disappoint in service. This piece walks through the three pore-forming routes behind SINOKLE KHC-F1001, also designated KHC-PC1001, the cobalt-nickel dual-atom active site design, and the performan

What Makes a Filter Medium Truly Super-Hydrophilic? The Surface Chemistry Behind SFM Modified Quartz Sand

2026-09-09

A close look at SFM super-hydrophilic modified quartz sand: how covalent grafting of hydroxyl, carboxyl and sulfonic groups builds an 8 nm hydration layer, pulls the contact angle below 5 degrees, and changes the way emulsified oil is demulsified and coal

Emulsified Oil Has Five Ways to Escape a Separator. The KHC Design Closes Each One.

2026-09-09

The KHC coalescing oil-water separator, developed independently by SINOKLE Technology in Shenzhen, stacks five mechanisms into one chain: super-oleophilic hydrophobic coalescing fiber, swirl centrifugal separation, wetting coalescence, collision coalescen

Four Mechanisms and One Plumbing Detail: Inside a Coalescing Oil Remover Above 99.9%

2026-09-09

A coalescing oil remover that holds oil removal above 99.9% is not a mystery box. It is coalescence media, shallow-pond geometry, a CFD-optimised flow field, patented packing, and one sand-flushing line that decides whether it survives real service. This

One Skid Instead of Three: Putting Ozone Oxidation and Flotation in the Same Shell

2026-09-09

Oxidation and separation are conventionally two process steps in two vessels. CDOF runs advanced oxidation and cyclonic dissolved-air flotation together inside one sealed pressurised skid. This article works through the five systems and seven synergistic

Under 90 Seconds: How a Cyclone Field Rewrites Flotation Economics

2026-09-09

The CFU compact flotation unit replaces gravity-field flotation with a centrifugal field, cutting retention time from 10-15 min to under 90 s and pushing single-stage oil removal past 80%. This article walks through the coupling logic, eight engineering a

Four Mechanisms, One Shell: What Actually Happens Inside a CDFU Vessel

2026-09-09

A CDFU unit is not four technologies bolted end to end. Cyclone, ultra-fine bubbles, dissolved air and coalescence demulsification operate simultaneously in one sealed vessel and reinforce each other. This piece takes each mechanism apart and traces where

250 m3/h Produced Water Down to Under 5 mg/L: The Five-Stage Chain Behind an African Oilfield

2026-09-09

Phase two of an integrated oilfield wastewater project in Africa treats 250 m3/h and discharges <5 mg/L of oil. This is a stage-by-stage technical read of the five-unit chain behind that figure: CDFU, coagulation-sedimentation, CDOF ozone catalytic oxi

Refinery Sour Water: Building a Three-Stage Train Down to 0.1 Micron Oil Removal

2026-09-09

Refinery sour water carries fine coke powder, heavily emulsified oil, sulfides and ammonia at fluctuating strength. SINOKLE's three-stage answer puts CDFU cyclonic flotation first, fine filtration second and a KHC coalescing separator third, reaching 0.1

Heavy Fuel Oil Plant Effluent: Why One Flotation Stage Never Holds at 2000 mg/L

2026-09-09

Oily wastewater from heavy fuel oil power stations runs high in oil, heavily emulsified and awkward to treat at acceptable cost. This is a stage-by-stage look at the plant SINOKLE delivered in Bangladesh for BR powergen limited: influent 2000mg/L, effluen
